Automation and deployment patterns

Many of us are used to logging onto a machine via ssh and grepping through log files to look for problems. Our worlds are now turned upside down since there are no longer any servers to SSH into. Fortunately, there are methods of handling errors and getting the information needed to debug and monitor your programs. 

In Chapter 9, Deployment and CI/CD Patterns, we'll focus on error handling, as well as some of the dos and don'ts of serverless systems and what modern-day best practices look like in the serverless world. Many development practices change when building on top of a serverless platform and there are a lot of gotchas that, if you're unfamiliar with them, may surprise you. Chapter 9, Deployment and CI/CD Patterns, will walk through some of the biggest issues that may bite you if you're brand new to this ecosystem.

While some tooling and techniques may change, let's not forget a healthy software development life cycle consists of well-structured code, continuous integration (CI), continuous deployment (CD), and unit tests. Coupled with the myriad of hosted CI/CD platforms, running tests and deploying code automatically is quite painless and even fun. In Chapter 10, Deployment and CI/CD Patterns will discuss various options and examples with hosted CI and CD platforms. I'm confident that you'll find the velocity at which you can ship code using serverless technologies exciting and enabling.
